Children’s skill at recoding graphemes to phonemes is widely understood as the driver of their progress in acquiring reading
vocabulary. This recoding skill is usually assessed by children’s reading of pseudowords (e.g., yeep) that represent “new words.” This study re-examined the extent to which pseudoword reading is, itself, influenced by orthographic
rimes (e.g., eep) of words of the child’s reading vocabulary, during the development of reading skill. In Study 1, children with word reading
levels of 6–10 years read matched pseudowords that do and do not share an orthographic rime with words of their reading vocabularies.
Study 2 was conducted to further examine such a comparison for children of the 6- to 8-year word reading levels. There was
a small and constant advantage of shared lexical orthographic rimes for children with reading levels 6–8 years but from 8
to 10 years that advantage increased significantly, as expected by Ehri’s phase account of word reading development. The pseudoword
reading of children learning to read English involves use of lexical orthographic components as well as context-free recoding
of graphemes to phonemes. This implies a qualification to the common interpretation of pseudoword reading as a measure of
context-free grapheme–phoneme recoding. Such a measure should use selected pseudowords that do not share orthographic rime
units or other multigrapheme components with words of the children’s reading vocabularies. 相似文献

Many theories of giftedness either explicitly or implicitly acknowledge the role of genetic influences; yet, empirical work has not been able to establish the impact that genes have specifically on gifted behavior. In contrast, a great deal of research has been targeted at understanding the etiology of individual differences in general and specific cognitive abilities across the entire range of ability and to a lesser extent, high cognitive ability. This paper attempts to outline what we know and what we don't know about the etiology of giftedness as operationally defined as high g. We review studies selected to represent a variety of approaches that each address a different question about genetics and giftedness. These studies include quantitative genetic research which estimate heritability, shared and nonshared family environment – at the high and low ends of intelligence – as well as the heritability of group differences for general cognitive ability and specific cognitive abilities. We discuss the molecular genetic methods and mechanisms contributing to cognitive ability and suggest how epigenetic factors may operate. Quantitative and molecular genetic studies that include endophenotypes representing intelligence at a level closer to the genotype, are also included. This last group of studies represent a relatively new area of work that builds on and extends the extensive groundwork established by classic quantitative genetic studies of behavior. 相似文献

Social class and participation in further education: evidence from the Youth Cohort Study of England and Wales 总被引:1,自引:1,他引:1
Ron Thompson 《British Journal of Sociology of Education》2009,30(1):29-42
This paper examines the class distribution of young people, aged 16–17 years, in colleges of further education (FE) using data from the Youth Cohort Study. It finds that, contrary to popular perceptions of FE colleges as being for ‘other people’s children’, middle‐class students as well as working‐class students are well represented. However, this does not imply that FE colleges are institutions of choice; middle‐class representation is often related to lower achievement and, for low‐achieving working‐class students, leaving education entirely is more likely than entry to FE. These findings are explored using notions of habitus and field. Their relationship with studies of the education of middle‐class children is also discussed, and the paper suggests that research on class in FE colleges must come to terms with middle‐class presence. 相似文献

A meta‐analysis was conducted with 65 school‐based psychotherapy and counseling dissertations over the last 10 years (1998–2008) to assess if a file‐drawer problem (i.e., studies conducted but not published that, as a whole, have different results than studies in the same area published) exists in the school‐based outcome literature. An overall mean effect size of 0.44 was found for 73 treatment interventions. This effect size is comparable to Prout and DeMartino's 1986 meta‐analysis conducted with published school‐based studies and approximately half a standard deviation smaller than Prout and Prout's 1998 meta‐analysis of school‐based intervention studies. A bias does appear to exist but seems to be smaller than the bias found in the general child and adolescent psychotherapy outcome literature. Most of the dissertation studies evaluated group interventions and used a cognitive–behavioral or skills training intervention. Skills training and interventions with elementary‐school students yielded the largest effect sizes. Comparisons of the current study with previous school‐based intervention meta‐analyses are discussed as are suggestions for future research. © 2010 Wiley Periodicals, Inc. 相似文献

We examined the Simple View of reading from a behavioral genetic perspective. Two aspects of word decoding (phonological decoding
and word recognition), two aspects of oral language skill (listening comprehension and vocabulary), and reading comprehension
were assessed in a twin sample at age 9. Using latent factor models, we found that overlap among phonological decoding, word
recognition, listening comprehension, vocabulary, and reading comprehension was primarily due to genetic influences. Shared
environmental influences accounted for associations among word recognition, listening comprehension, vocabulary, and reading
comprehension. Independent of phonological decoding and word recognition, there was a separate genetic link between listening
comprehension, vocabulary, and reading comprehension and a specific shared environmental link between vocabulary and reading
comprehension. There were no residual genetic or environmental influences on reading comprehension. The findings provide evidence
for a genetic basis to the “Simple View” of reading. 相似文献

As university involvement in technology transfer and entrepreneurship has increased, concerns over the patenting and licensing of scientific discoveries have grown. This paper examines the effect that the licensing of academic patents has on journal citations to academic publications covering the same scientific research. We analyze data on invention disclosures, patents, and licenses from the University of California, a leading U.S. academic patenter and licensor, between 1997 and 2007. We also develop a novel “inventor-based” maximum-likelihood matching technique to automate and generalize Murray's (2002) “patent-paper pairs” methodology. We use this methodology to identify the scientific publications associated with University of California patents and licenses.Based on a “difference-in-differences” analysis, we find that within our sample of patented academic discoveries, citations to licensed patent-linked publications are higher in the three years after the license, although this difference is not statistically significant. We then disaggregate our sample into (a) patented discoveries that are likely to be used as “research tools” by other researchers (based on the presence of material transfer agreements (MTAs) that cover them) and (b) patented discoveries not covered by MTAs. Citations to publications linked to licensed patents in the latter subset (not covered by MTAs) are higher for publications linked to licensed patents, and this difference is statistically significant. In contrast, licensing of patented discoveries that are also research tools is associated with a reduction in citations to papers linked to these research advances, raising the possibility that licensing may restrict the flow of inputs to “follow-on” scientific research. 相似文献

The primary aim of this study was to determine whether facial feature tracking reliably measures changes in facial movement across varying exercise intensities. Fifteen cyclists completed three, incremental intensity, cycling trials to exhaustion while their faces were recorded with video cameras. Facial feature tracking was found to be a moderately reliable measure of facial movement during incremental intensity cycling (intra-class correlation coefficient = 0.65–0.68). Facial movement (whole face (WF), upper face (UF), lower face (LF) and head movement (HM)) increased with exercise intensity, from lactate threshold one (LT1) until attainment of maximal aerobic power (MAP) (WF 3464 ± 3364mm, P < 0.005; UF 1961 ± 1779mm, P = 0.002; LF 1608 ± 1404mm, P = 0.002; HM 849 ± 642mm, P < 0.001). UF movement was greater than LF movement at all exercise intensities (UF minus LF at: LT1, 1048 ± 383mm; LT2, 1208 ± 611mm; MAP, 1401 ± 712mm; P < 0.001). Significant medium to large non-linear relationships were found between facial movement and power output (r2 = 0.24–0.31), HR (r2 = 0.26–0.33), [La?] (r2 = 0.33–0.44) and RPE (r2 = 0.38–0.45). The findings demonstrate the potential utility of facial feature tracking as a non-invasive, psychophysiological measure to potentially assess exercise intensity. 相似文献
